"Sagitta, (pronounced Sag-ee-tah) is a Latin word meaning arrow... The design is conventional in appearance with careful attention paid to minimizing aerodynamic drag and improving efficiency. Construction utilizes conventional model materials and techniques, with structural design optimized to provide a rugged airframe. This design can be easily duplicated by anyone who has a flat bench and who has already built a simpler ship, such as the Olympic II. Some additional time and effort in carving and sanding are required to develop the smooth flowing contours of the Sagitta, but the aesthetic and aerodynamic benefits are well worth the extra trouble... Two major considerations influenced the design of the Sagitta: First, to improve the flight performance of the Aquila and Aquila Grande; second, to allow complete access to the radio equipment and ballast without using any tools. In addition, we wanted to improve the spoiler hook up system used on the Aquilas. These requirements led to the forward hatch and hinged access panel which provide excellent fuselage access, and simple spoiler hookup as well as wing retention. As a bonus, the towhook becomes readily accessible, simplifying adjustment of releasable towhooks. The fuselage design provides minimal frontal area and wetted surface for decreased drag. The shoulder mounted wing position eliminates two intersections, and the obtuse angle between the fuselage sides, and wing lower surface makes wing fillets unneccessary. The slim aft cross-section is possible through the use of stranded cable inside tubing pushrods. The side and plan view outlines represent the minimum envelope consistent with equipment space requirements and structural requirements. Two ballast compartments are provided, which perm it the flier to more than double the the model's weight. Full length poplar ply sides with spruce longerons provide plenty of strength and rigidity. Of course the heart of any sailplane design is the wing. Sagitta utilizes a relatively low aspect ratio to raise the Reynolds Number and to pack 900 square inches into a 100" span. This approach has been proven in practice by the success of the Aquila and Oly II in Standard Class competition. Wing planform is contant chord center panels with double tapered tips. The center and tip panels are equal in span for better turning charactertistics due to improved structure and moments of inertia. The sharply raked tips provide low drag with distinctive, appearance. Polyhedral is used for quick turn response with rudder/elevator control. The shallow center angle and increased tip angles improve efficiency and give better response..."
